System and process for cleaning a jet engine component

ABSTRACT

This invention relates to a system and process for cleaning a jet engine component and, more particularly, a system and process for cleaning the inside surfaces of a jet engine component.

BACKGROUND OF THE INVENTION 1. Field of the Invention

This invention relates to a system and process for cleaning a jet engine component and, more particularly, a system and process for cleaning the inside surfaces of a jet engine component.

2. Description of the Related Art

In the field of aviation, the use of jet engines is well-known. Jet engines typically comprise many components, such as a turbine spools or disks, that periodically need to be cleaned and polished and their surfaces inspected for defects. The turbine engine components are typically disassembled and then hand cleaned so that any residual contamination inside the components can be removed. Unfortunately, many of the surfaces inside the components are difficult for a person to reach or see for inspection.

Oftentimes, these areas are very narrow, and sometimes too narrow, to get a human hand in to polish the contaminated surfaces. To date, the industry has used paint stir sticks with abrasive pads glued to the ends to polish the surfaces. Unfortunately, the effectiveness of the prior art approaches was not dependable and was oftentimes inaccurate because the person performing the cleaning cannot see in the areas and the surfaces that need to be cleaned.

Another problem with the prior art approaches to cleaning the inside of the surfaces was the time it took to do so. In the past, it would typically take four to five hours to clean a single part manually.

What is needed therefore is a system and method of cleaning, scrubbing and polishing the inside of a part, particularly where the areas of the surfaces to be cleaned are narrow.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring now to FIG. 1 , a turbine engine component cleaning system and process 10 is shown. The turbine engine component cleaning system and process 10 is adapted particularly for use with cleaning a turbine engine component or part 12 (FIG. 9 ) that comprises a plurality of surfaces 12 a that need to be cleaned. In some embodiments, the turbine engine component cleaning system and process 10 cleans all geometry of surfaces, parallel, non-parallel, perpendicular, uneven, flat or planar, non-planar and the like. The turbine engine component cleaning system and process 10 comprises a frame 14 having a plurality of channel members 14 a-14 d that are assembled and fastened or welded together to provide a support base 16 for supporting the components of the turbine engine component cleaning system and process 10. Notice that at least two frame components, such as frame components 14 a and 14 c in FIG. 7 , have interior walls 14 a 1 and 14 c 1 that each define a first aperture 18 and a second aperture 20, respectively, that are sized and adapted to receive forks (not shown) of a forklift truck or other device lifting and/or moving the turbine engine component cleaning system and process 10.

The support base 16 may comprise a plurality of wheels, such as rotatable caster wheels 22, so that the turbine engine component cleaning system and process 10 is portable and easily moved by hand. In this regard, the turbine engine component cleaning system and process 10 further comprises a plurality of vertical support posts 24 that support a generally planar support plate 26 as shown. A handle 28 is secured to the support plate 26 by conventional means, such as a weld, fastener or the like, and comprises a first generally horizontal support component 30 for grasping when moving the turbine engine component cleaning system and process 10 to a desired position. Notice that the handle 28 also comprises a second generally horizontal support component 32 that is adapted to receive and support a control and switch box 34 for controlling an operation of the turbine engine component cleaning system and process 10 in a manner described later herein.

The turbine engine component cleaning system and process 10 further comprises a riser assembly 29 (FIG. 1 ) having a generally cylindrical first support plate 36 that is conventionally mounted on the support plate 26 and comprises a plurality of support columns 38 as shown. The support columns 38 support a generally cylindrical second support plate 40 that is generally parallel and opposes the first support plate 36. The plurality of support columns 38 cause the second support plate 40 to be spaced a predetermined distance from the first support plate 36. Although not shown, it should be understood that a second plurality of support columns 38 of different lengths could be provided, selected and adapted to change the predetermined distance at which the first support plate 36 is separated from the second support plate 40. The predetermined distance may be determined in part by the turbine engine component or part 12 being wiped, scrubbed or polished by the turbine engine component cleaning system and process 10. In this example, the predetermined distance is about 14 inches.

As best illustrated in FIG. 8 , note that a drive motor 52 is conventionally mounted on the support plate 26. In the illustration being described, the drive motor 52 is an AC motor ½ HP and comprises an M1 mounting, but other types and sizes of motors could be used. The drive motor 52 receives power from a conventional power supply (not shown) that is coupled to and under the control of the control and switch box 34 mentioned earlier. In this regard, the control and switch box 34 comprises an on/off button or switch 34 a, an emergency stop button or switch 34 b and an activation light 34 c for allowing a user to know when the turbine engine component cleaning system and process 10 is active.

Referring now to FIGS. 8, and 8A-8C, notice that the drive motor 52 comprises a primary drive shaft 54 that has a splined end 54 b secured thereto and that receives a drive shaft extension 54 a (FIGS. 8, 8A-8C and 9 ). The motor 52 is conventionally mounted to an underside 26 a of the support plate 26. Notice that a spindle or bearing assembly 56 is mounted on a top surface 26 b of the support plate 26 and comprises an outer support collar or sleeve 56 a that is mounted onto the support plate 26 using conventional bolts 76 as illustrated in FIG. 8C. The spindle or bearing assembly 56 comprises a plurality of bearings 58 that are secured to the support plate 26 with fasteners 77. A support collar 55 is also mounted onto the drive motor 52 and the underside 26 a of the support plate 26. The support collar 55 is a spacing block to provide space between the support plate 26 and the drive motor 52 for the spline and motor coupling components. Additional bearings 58 a, 58 b and a sleeve 58 c are received on the drive shaft 54 and secure the end 54 b to the drive shaft 54.

As best illustrated in FIGS. 8, 8A-8C and 9 , the drive motor 52 rotatably drives the primary drive shaft 54 that is supported and received in the bearing assembly 56. Notice that the first and second support plates 36 and 40 comprise an interior wall 36 a and interior wall 40 a, respectively, that define apertures 42 and 44, respectively. The primary drive shaft 54 is rotatably mounted to or received in the bearing assembly 56 which maintains the primary drive shaft 54 in a generally centrally-located position in both the apertures 42 and 44 as shown.

In the example, the primary drive shaft 54 is coupled to a pneumatic manifold assembly 59 (FIG. 11 ) via the drive shaft extension 54 a, both of which will be described in more detail later herein.

The bearing assembly 56 comprises the outer support collar or sleeve 56 a that is sized and adapted to engage, receive and support a wall 70 a of the turbine engine component of part 12 to be scrubbed, polished or cleaned. In this regard, the turbine engine component cleaning system and process 10 is primarily adapted for use in cleaning the turbine engine components or parts 12 that have the plurality of surfaces 12 a to be cleaned, but it could be used with other parts (not shown) other than turbine engine components. Note that the surfaces 12 a may be generally parallel spaced surfaces, such as the plurality of surfaces 12 a mentioned earlier herein, but they could be non-parallel, perpendicular, planar, non-planar, interrupted, circular, non-circular and the like.

FIGS. 2, 2A-2C and 8A-8C show one illustration of the turbine engine component or part 12 mounted and supported on the bearing assembly 56 (FIG. 9 ). Of course, it should be understood that the support collar or sleeve 56 a is fastened to the support plate 26 with the bolts 76 (FIG. 8B) and is stationary during operation. The outer support collar or sleeve 56 a is adapted to be changed if necessary with another collar or sleeve (not shown) that is sized and adapted to fit a second turbine engine component or part (not shown) having similar or different surfaces to be scrubbed, cleaned or polished.

Referring now to FIGS. 2A-2D, details of one example of the part 12 are shown. It should be understood that while this part is a turbine engine component, the turbine engine component cleaning system and process 10 may be used with other parts 12 (not shown) that are in need of having surfaces being cleaned and scrubbed. Notice in the sectional view of FIG. 2B that the part comprises the plurality of surfaces 12 a to be cleaned. In this exemplary embodiment, notice that the surfaces 12 a are generally parallel and some of the surfaces oppose each other, as illustrated. It should be understood, however, that the surfaces 12 a do not always have to be parallel and they can be perpendicular or spaced. Notice that support and centering locators 72, 73 (FIG. 2B) have internal walls 72 a and 73 a that define recessed areas 72 b and 73 b that are adapted, sized and complementary shaped to receive a bottom portion or edge 12 d of the part 12, as illustrated. Note that one or more locating pins 73 c or fasteners may be used to secure the part onto the support and centering locators 72, 73. Thus, the turbine engine component cleaning system and process 10 comprises the pair of support and centering locators 72, 73 that are adapted and sized to receive and support at least a portion of the turbine engine component or part 12 (FIG. 9 ) to be cleaned.

As illustrated, the walls 72 a and 73 a cooperate to define a circumference and shape that generally complements a circumference and shape defined by an edge 12 d of the turbine engine component or part 12. Accordingly, the locators 72 and 73 not only cooperate to locate the turbine engine component or part 12 on the second support plate 40 of the riser assembly 29, but also stabilize the turbine engine component or part 12 during the polishing, scrubbing and/or cleaning process. During operation of the turbine engine component cleaning system and process 10, the turbine engine component or part 12 remains fixed and stationary after the turbine engine component or part 12 is mounted on the centering locators 72, 73. In this regard, at least one or a plurality of anti-rotation pins or bolts (not shown) may be used to secure and stabilize the turbine engine component or part 12 on the support and centering locators 72, 73 and/or on the support plate 26.

In general, after the turbine engine component or part 12 is mounted on the support and centering locators 72, 73 and fastened thereto, the pneumatic manifold assembly 59 is then assembled and mounted onto the drive shaft extension 54 a. Notice in FIG. 11 that the drive shaft 54 and drive shaft extension 54 a have a drive shaft axis (labeled A in FIG. 11 ) that is generally centrally located in the apertures 42 and 44 without the pneumatic manifold assembly 59 mounted thereon. During use, the user first positions and secures the turbine engine component or part 12 onto the support and centering locators 72, 73 which, in turn, causes the axis A of drive shaft 54 of the drive motor 52 to be generally centrally located inside the turbine engine component or part 12. Thereafter, the pneumatic manifold assembly 59 is then mounted on the drive shaft 54 and a locking plate 80 (described later) is mounted onto the pneumatic manifold assembly 59 and the turbine engine component or part 12 in a manner described later herein. It should be understood that the locking plate 80 locks the relative position of the pneumatic manifold assembly 59 and the drive shaft 54 relative to the turbine engine component or part 12. It should be understood that the entire pneumatic manifold assembly 59 and drive shaft extension 54 a may be assembled together and then mounted onto the drive shaft 54 after the turbine engine component or part 12 is mounted on the locators 72 and 73.

The pneumatic manifold assembly 59 comprises at least one or a plurality of support blocks 92 that are adapted to receive and support at least one or a plurality of stackable drive blocks 94, 96, 98 and 100 as shown. Each of the plurality of stackable drive blocks 94-100 support at least one or a plurality of cleaner assemblies 102 that are selectively and detachably mounted to the at least one or a plurality of the stackable drive blocks 94-100 as shown and described herein. The plurality of stackable drive blocks 94-100 nest and stack together as shown. In this regard, note that each of the plurality of stackable drive blocks 94-100 have a generally rectangular projection, such as a male projection 103 (FIG. 14A) that is received in a complementary-shaped rectangular aperture 101 (FIG. 14A) defined by a wall 99 in the support block 92. It should be understood that each stackable drive block 96-100 can be stacked in any order on top of each other and/or on support block 92. Consequently, each stackable drive block 94-100 has the male projection 103 and the rectangular aperture 101.

In this example, each of the plurality of cleaner assemblies 102 comprises at least one paddle 104 and at least one inflatable air bag 106 that is coupled to the at least one paddle 104 in the manner described herein. Note that the paddle is generally U-shaped and comprises arms 104 a, 104 b (FIGS. 14 and 15 ) joined by a joining portion 104 c. Each joining portion 104 c (FIGS. 13-14E) may optionally have at least one of the inflatable air bags 106 coupled thereto. The at least one paddle 104 and air bag 106 are adapted to receive and comprise a pad, scrubber, sock, cover or bag 107 (FIG. 14 ), which in the illustration being described is a Scotch-Brite™ cover that is placed over the at least one paddle 104 as illustrated. For ease of illustration, part 107 will collectively be referred to as a bag.

In the illustration being described and during use, after the pneumatic manifold assembly 59 is mounted to the drive shaft extension 54 a, which is mounted on the drive shaft 54, and the locking plate 80 is mounted thereon, notice that the at least one or a plurality of paddles 104 and their inflatable air bags 106 are positioned in operative relationship with the at least one or plurality of surfaces 12 a to be polished, scrubbed or cleaned, as illustrated in FIGS. 1, 2, 7 and 9 . Thereafter, the inflatable air bags 106 may be inflated which urges or causes the bag 107 to engage one or both of the opposing surfaces 12 a of the turbine engine component or part 12 being cleaned so that when the drive motor 52 is energized, the pneumatic manifold assembly 59 rotates which causes the at least one paddle 104 to rotate and polish, scrub and/or clean the plurality of surfaces 12 a of the turbine engine component or part 12 to be cleaned.

Once the turbine engine component or part 12 is mounted on the support and centering locators 72, 73 (see FIGS. 2 and 9 ) and the pneumatic manifold assembly 59 is mounted on the drive shaft 54 and the locking plate 80 is mounted on the pneumatic manifold assembly 59, the user may actuate the switch 34 a (FIG. 4 ) which causes the drive motor 52 to rotatably drive the entire pneumatic manifold assembly 59. In order to maintain stability and to supply fluid to the pneumatic manifold assembly 59, an air delivery shaft 112 is mounted or coupled to the last one of the stackable drive blocks 94-100, namely block 100 in the example shown in FIG. 9 . The locking plate 80 has a bearing 113 that is sized and adapted to receive the air delivery shaft 112 and support the pneumatic manifold assembly 59 during rotation of the pneumatic manifold assembly 59 as shown.

It should be understood that the number of the plurality of stackable drive blocks 94-100 and the plurality of cleaner assemblies 102 that are used and mounted on the at least one or a plurality of stackable drive blocks 94-100, is dependent, in part, upon the turbine engine component or part 12 and its plurality of surfaces 12 a to be cleaned. Notice in the illustration in FIG. 8 that four stackable drive blocks 94-100 are used and support a plurality of the cleaner assemblies 102. FIG. 8 shows the stackable drive blocks 94, 96, 98 and 100 each having a pair or a plurality of the cleaner assemblies 102 mounted thereto. In contrast, the stackable drive block 96 shows only one cleaner assembly 102 mounted thereto, but two paddles 104 mounted thereto. The paddle 104 does not have an air bag 106 mounted thereto. It should also be understood that the number of stackable drive blocks 94-100 used may change and more or fewer stackable drive blocks 94-100 may be used and will depend upon the turbine engine component or part 12 being cleaned, scrubbed or polished.

Thus, it should be understood that once the number of stackable drive blocks 94-100 are selected, they are stacked as shown. The locking plate 80 is mounted on the turbine engine component or part 12 and rotatably supports the air delivery shaft 112 that is mounted on the last of the stackable drive blocks 94-100, which in the illustration, is stackable drive block 100. The air delivery shaft 112 is adapted to be coupled to a pneumatic air supply 119 with an air hose 120 (FIG. 5 ) as shown. It should be understood that the plurality of stackable drive blocks 94-100 each have a pneumatic channel or conduit which permits delivered air to pass from the pneumatic air supply 119 (FIGS. 8 and 9 ) into and through the plurality of stackable drive blocks 94-100. The plurality of stackable drive blocks 94-100 delivers the air to the plurality of paddles 104 and air bags 106 so that they can be inflated when desired. The pneumatic delivery system and the conduits in the plurality of stackable drive blocks 94-100 that enable air to be delivered to the plurality of cleaner assemblies 102 will now be described.

FIGS. 10 and 11 are views of an embodiment having only two of the stackable drive blocks 94-100 for ease of illustration. Notice in FIG. 12 that the support block 92 is coupled to the drive shaft extension 54 a by conventional means, such as a splined connection or end, a weld or a threaded connection. The drive shaft 54 is conventionally coupled to a first end 54 a 1 (FIG. 11 ) of the drive shaft extension 54 a, which couples the drive shaft 54 and the drive shaft extension 54 a directly to the drive motor 52, with the opposite end 54 b being coupled directly to the support block 92. As mentioned earlier, the outer support collar or sleeve 56 a (FIGS. 8, 8A-8C and 9 ) of the bearing assembly 56 is mounted on the support plate 26 and rotatable supports of the drive shaft extension 54 a and the sleeve 56 a simultaneously engage and support the interior wall 70 a of the turbine engine component or part 12 that is received in and supported by the outer support collar or sleeve 56 a. The outer support collar or sleeve 56 a is mounted to the support plate 26 using conventional bolts 76 (FIG. 8B) as shown.

Thus, in the illustration being described, the outer support collar or sleeve 56 a provides lateral and rotary support for the drive shaft 54 and drive shaft extension 54 a as they rotate in the bearing assembly 56, as well as stabilizing support for the turbine engine component or part 12 during operation.

Referring back to FIGS. 7-11 , the end 54 b of the drive shaft extension 54 a comprises the support block 92 to the drive shaft extension 54 a. The support block 92 (FIG. 11 ) comprises an internal generally rectangular wall 92 d (FIG. 11 ) that defines a generally rectangular recessed area 95 for receiving a complementary-shaped male projection or extension 98 c of one of the at least one of the plurality of stackable drive blocks 94-100 as shown. For example, notice in the example in FIG. 8 that the stackable drive block 94 is simply stacked and mounted directly on top of the support block 92 and stackable drive block 96 is stacked and mounted directly onto the stackable drive block 94. Further explanation of the stabilizing and mounting of the plurality of stackable drive blocks 94-100 is shown in the example of FIGS. 13-14B. Thus, if multiple levels of cleaning and scrubbing are necessary in the turbine engine component or part 12, then other stackable drive blocks, such as stackable drive blocks 96-100, can be directly mounted or stacked onto the stackable drive block 94 or each other as shown. The number of stackable drive blocks 94-100 that are mounted onto the support block 92 is determined and selected in response to the turbine engine component or part 12 and its plurality of surfaces 12 a that are to be cleaned or scrubbed.

After the turbine engine component or part 12 is mounted on the locators 72, 73, the plurality of stackable drive blocks 94-100 are selected, stacked and assembled as shown, they are secured and conventionally fixed to the support block 92, such as by the use of bolts 93 (FIG. 14A) that pass or traverse through all of the plurality of stackable drive blocks 94-100 and are threaded into mating female apertures (not shown) in the support block 92. Thereafter, the fluid or air delivery shaft 112 is mounted on the last or top (as viewed in the Figures) stackable drive block 100, and the locking plate 80 is mounted or placed onto the turbine engine component or part 12. Notice that the locking plate 80 has a plurality of fasteners 110 that are generally L-shaped and grip the inside of or an inner wall 12 e (FIG. 2B) of the turbine engine component or part 12. It should be understood that the locking plate 80 and the turbine engine component or part 12 do not rotate during operation or while the plurality of stackable drive blocks 94-100 rotate during cleaning and scrubbing.

As mentioned earlier, each of the plurality of stackable drive blocks 94-100 have the same or similar pneumatic channel or conduit (labeled 100 d in FIG. 14A for stackable drive block 100). The channels or conduits of each stackable drive block 94-100 become coupled together and in fluid communication when the plurality of stackable drive blocks 94-100 are stacked so that each of the conduits from each of the stackable drive blocks 94-100 cooperate to define a continuous conduit or passageway adapted to deliver fluid, such as air, from the pneumatic air supply 119 (FIG. 8 ) to each of the stackable drive blocks 94-100 and any of the inflatable air bags 106 that may be attached to any one of the plurality of stackable drive blocks 94-100. Before the locking plate 80 is mounted on the last or top stackable drive block 100, an end 112 e (FIG. 11 ) of the air delivery shaft 112 is mounted in a generally U-shaped channel 100 b of the top stackable drive block 100 as shown. The air delivery shaft 112 has a conduit 112 b and a valve 112 a for coupling to the air hose 120 (FIG. 5 ) that is coupled to the pneumatic air supply 119 that delivers air to an air regulator 122 (FIG. 5 ) and the air delivery shaft 112.

Notice in FIG. 11 that the conduit 112 b in the air delivery shaft 112 extends the entire length of the air delivery shaft 112, and a coupler end 112 c comprises a conventional air relief valve 115. As alluded to earlier, note that the coupler end 112 c has the generally rectangular male projection or end 112 e that is received in and mates with the complementary-shaped female aperture or channel 100 b (FIG. 11 ). Thus, the end 112 e of the air delivery shaft 112 is sized and adapted to fit in the area or channel 100 b in the stackable drive block 100 as shown.

Each of the stackable drive blocks 94-100 comprises a generally L-shaped air conduit, such as the air conduit 100 d in stackable drive block 100, defined by an internal wall 100 d 1 that permits air to pass into and through the stackable drive block 100 and to any air bags 106 that are coupled thereto. Notice that when the air delivery shaft 112 is mounted onto the stackable drive block 100, the conduit 112 b becomes in fluid communication with the conduit 100 d so that air from the pneumatic air supply 119 (FIG. 8 ) can be delivered through the air delivery shaft 112 and into the stackable drive block 100 and ultimately to any inflatable air bag 106 that is coupled to the stackable drive block 100.

Returning to FIGS. 8-11 , note that each stackable drive block 94-100 comprises an air valve 117 which in the illustration being described, is a Schrader valve, which is similar to a conventional bicycle tire valve. All stackable drive blocks 94-100 have a similar configuration and air valve 117 and their respective conduits become coupled in fluid communication with each other when the stackable drive blocks 94-100 are stacked. This enables any air bags 106 coupled to the stackable drive blocks 94-100 to become inflated when the turbine engine component cleaning system and process 10 is energized.

Features of the stackable drive blocks 94-100 and various cleaner assemblies 102 will now be described relative to the stackable drive blocks 98 and 100 shown in FIGS. 10-14A, but it should be understood that each of the stackable drive blocks 94-100 are similarly constructed. As illustrated in FIG. 11 , notice that each of the plurality of paddles, such as paddle 104 in FIG. 11 , comprises the air valve 117 (FIG. 14 ) that engages and depresses the air valve 117 on one of the stackable drive blocks 94-100 when the paddle 104 is mounted to a stackable drive block 94-100 as shown. It should be appreciated that each of the air valves 117 is normally closed, but becomes activated to the open position by a nipple or raised projection 104 d when the paddle 104 is mounted on the stackable drive block 100.

Note in FIGS. 14A-14B, that the stackable drive block 100 and adjacent stackable drive block 98 have surfaces, such as the surfaces 100 b and surfaces 98 b in FIG. 11 , respectively, that cooperate to define a generally rectangular aperture or area 111 (FIG. 11 ) that is sized and adapted to receive an end 104 c 1 of paddle 104. Once inserted in the area 111, the nipple or raised projection 104 d urges or depresses the air valve 117 into an open position so that air can flow into stackable drive block 100 and the paddle 104 attached thereto and then inflate the air bag 106. Thus, once the paddles 104 are mounted onto one or more of the stackable drive blocks 94-100, the nipple or raised projection 104 d depresses the air valve 117 to permit air to pass into and through the stackable drive blocks 94-100 and into any air bags 106 coupled thereto. Each paddle 104 comprises a paddle conduit 121 a that receives air from the channel 100 d and permits the air to pass into the inflatable air bag 106 attached to the paddle 104. This, in turn, causes the air bag 106 to inflate.

The air bag 106 may comprise the bag 107 (FIGS. 13, 14 and 14B) that is situated over the air bag 106 so that it can engage the at least one or a plurality of surfaces 12 a on the turbine engine component or part 12 to be cleaned. In one embodiment, the air bag 106 is a rubber bladder or bag adapted to inflate and deflate. Notice in FIG. 11 that when the stackable drive block 100 is mounted on the stackable drive block 98, the conduit 100 d becomes connected to and in fluid communication with an air conduit or passageway 98 a of the stackable drive block 98. The air conduit or passageway 98 a of the stackable drive block 98 is in fluid communication with the paddle conduit 121 a so that air delivered through the air delivery shaft 112 passes into and through the stackable drive block 100, the conduit or channel 100 d and into the passageway 98 a of stackable drive block 98 so that air can be delivered to and inflate the air bag 106 coupled to the paddle 104 which is coupled to stackable drive block 98. As with the paddle 104 coupled to block 100, note that the paddle 104 also has the nipple or raised projection 104 d that actuates or depresses the air valve 117 so that the passageway 98 a becomes connected to and in fluid communication with the channel 100 a of block 100. Although not shown, it should be understood that more or fewer passageways 100 b, 98 a may be provided in each of the stackable drive blocks 94-100, depending on the turbine engine component or part 12 to be cleaned.

For comparison, notice that the embodiment of FIGS. 8 and 9 illustrates the plurality of stackable drive blocks 94-100 stacked, with each having a plurality of paddles 104 coupled thereto and the conduit of each of the stackable drive blocks 94-100 in fluid communication so they can permit air to be delivered to the air bags 106 coupled to the paddles 104.

Once the turbine engine component or part 12 is positioned and all desired stackable drive blocks 94-100 are stacked and their respective desired paddles 104 are mounted thereto, the turbine engine component cleaning system and process 10 may be energized by activating the switch 34 a (FIG. 4 ) on the switch box 34. The pneumatic air supply 119 supplies air to the air delivery shaft 112 which delivers the air into each of the stackable drive blocks 94-100, such as into the stackable drive block 100 and the stackable drive block 98 as shown. As shown in FIG. 7 , the turbine engine component cleaning system and process 10 comprises the regulator valve 122 (FIG. 5 ) for controlling cubic feet per minute (CFM) of the airflow into the air delivery shaft 112. The air regulator valve 122 controls the PSI that the air bags 106 use to engage the surfaces 12 a to be scrubbed, polished or cleaned.

For ease of illustration, the embodiment shown in FIGS. 10 and 11 only show two stackable drive blocks 98, 100 mounted onto the support block 92, but as previously mentioned, it should be understood that fewer or more stackable drive blocks 94-100 may be detachably stacked on top of each other and this will depend upon the turbine engine component or part 12 being cleaned. It should be appreciated that while each stackable drive block 94-100 is adapted to detachably receive at least one or a plurality of paddles 104, each of which have an inflatable air bag 106, it should also be understood that one or more of the stackable drive blocks 94-100 can be used without air bags 106 so that it is simply supporting an adjacent stackable drive block 94-100. For example, the stackable drive block 100 may have the paddle 104 detachably secured thereto, while an adjacent stackable drive block, such as stackable drive block 98 in FIG. 11 , has either none or only a single paddle 104 secured thereto.

Notice in embodiments of FIGS. 8 and 9 , a plurality of paddles 104 are mounted to each stackable drive block 94-100, while in the embodiment of FIG. 11 , the stackable drive blocks 98 and 100 each only support a single paddle 104 and air bag 106. If a stackable drive block 94-100 has no paddle, then that the air delivery conduit in the stackable drive block 94-100 will only deliver air to a subsequent or adjacent stackable drive block 94-100 if it exists and to any inflatable air bag 106 coupled thereto. If no paddles 104 are coupled, then the normally-closed air valves 117 prevent air from leaking outside any of the stackable drive blocks 94-100. FIG. 14B illustrates an inlet end 106 a coupled to the paddle 104 via a connector 121.

Referring now to FIGS. 10 and 11 , further details of the pneumatic passages or conduits will now be described relative to the stackable drive blocks 98 and 100, with it being understood that the other stackable drive blocks 94 and 96 are substantially the same in design and configuration. Notice that the drive shaft extension 54 a is coupled to the support block 92, which does not have any conduits, as described earlier herein. The first one, namely stackable drive block 98 of the plurality of stackable drive blocks 94-100, is mounted to the support block 92 as shown. The first stackable drive block 98 comprises the conduit or passageway 98 a. The stackable drive block 98 also comprises the plug 115 that seals the passageway 98 a and also provides access thereto. The air valve 117 mentioned earlier herein is seated in the passageway 98 a of the stackable drive block 98 as illustrated.

Notice that the stackable drive block 98 comprises the wall or surface 98 b that cooperates with an end wall 92 a on support block 92 to define a generally U-shaped channel or area 125 that is adapted to receive the portion 104 c of the paddle 104. As mentioned earlier, the paddle 104 comprise the paddle conduit 121 a (FIG. 11 ) that becomes in fluid communication with the conduit or passageway 98 a of the stackable drive block 98 to which it is attached when the paddle 104 is insertably and detachably mounted to their respective block, such as stackable drive block 98 or 100 in the example of FIG. 11 . Thus, the paddle 104 associated with stackable drive block 98 comprises the paddle conduit 121 a that is in direct fluid communication with both the conduit or passageway 98 a and at least one of the plurality of air bags 106 attached thereto. As mentioned earlier, each paddle 104 comprises the nipple or raised portion 104 d or portion 104 c that depresses the air valve 117 that resides in the stackable drive block 98. When the paddle end 104 c is inserted into the area 125, the nipple or raised projection 104 d depresses and opens the air valve 117 which opens up the passageway 98 a and causes it to be in fluid communication with the paddle conduit 121 a of the paddle 104. Of course, it should be understood that when the air valve 117 is not depressed by the nipple or raised projection 104 d on the paddle end or arm 104 c because the paddle 104 is not mounted on stackable drive block 98, it remains closed, yet the stackable drive block 98 will still deliver air or permit air to pass through passageway 98 a to any upstream or the downstream stackable drive blocks 94, 96 or 100.

Thus, it should be understood that the pneumatic conduits or passageways (for example, 98 a and 100 c in the embodiment of FIG. 11 ) in each of the stackable drive blocks 94-100 are in fluid communication when they are detachably stacked as shown. Each of the support block 92, the air delivery shaft 112, and the stackable drive blocks 94-100 may comprise at least one or a plurality of gaskets, O-rings or seals (not shown) that provide a seal between adjacent stackable drive blocks 94-100 and their respective conduits.

FIGS. 8, 8A-8C and 9 illustrate an embodiment showing a plurality of stackable drive blocks 94-100 with each stackable drive block 94-100 having a pair of the paddles 104 mounted thereon. The bag 107 mentioned earlier may be placed over both the paddle 104 and the air bag 106 so that when the air bag 106 is inflated, it forces the bag 107 against the surface or plurality of surfaces 12 a to be cleaned. When the drive motor 52 is energized, it rotates the entire assembly of stackable drive blocks 98-100 and their associated paddles 104 and bags 107 inside the part 12 and against the plurality of surfaces 12 a of the turbine engine component or part 12 after the air bags 106 are inflated, thereby scrubbing, cleaning and/or polishing the plurality of surfaces 12 a of the turbine engine component or part 12 to be cleaned.

As alluded to earlier, one or more of the stackable drive blocks 94-100 may be provided as a support, but without any air bag 106 or paddle 104 coupled thereto. It should be understood that a single paddle 104 and air bag 106 may be used or a plurality of paddles 104 and air bags 106 may be used, and this will largely depend upon the plurality of surfaces 12 a of the turbine engine component or part 12 to be cleaned. FIGS. 5, 10, 11, 14 and 14B illustrate bags 107 on each paddle 104 and FIGS. 6 and 8 show paddles with air bags connected, but without bags 107 placed on the paddles 104.

In one example, the turbine engine component or part 12 to be cleaned is a turbine engine coupling component that has the plurality of generally planar and cylindrical interior plurality of surfaces 12 a that lie in planes that are generally radial to the axis A of rotation of the drive shaft 54. As mentioned earlier herein, although the plurality of surfaces to be cleaned 12 a are generally planar, spaced, generally cylindrical and generally parallel, it should be appreciated that the plurality of surfaces 12 a may be spaced, interior, exterior, generally parallel, non-parallel, radial, perpendicular, arcuate, interrupted, polygonal or the like, as illustrated schematically in FIG. 2B. It should also be understood that at least one of the surfaces to be cleaned may be spaced from another surface to be cleaned, interior to s turbine engine component or part 12, generally parallel to another surface to be cleaned, non-parallel to another surface to be cleaned, radial, perpendicular, arcuate, interrupted, polygonal or the like. In one example, the turbine engine component or part 12 comprises the plurality of generally opposing surfaces 12 a illustrated in FIGS. 2B, 7 and 9 that are generally cylindrical and define at least one generally circular planar surface or plate that is interior to the housing 12 b (FIG. 9 ) of the turbine engine component or part 12.

Notice in FIGS. 14 and 14A-14C and as described herein that the stackable drive blocks 94-100 nest on top of each other as shown. For ease of illustration, further features of two of the blocks, namely stackable drive blocks 98 and 100, will be shown and described relative to FIG. 14A, but it should be appreciated that these features reside in the other stackable drive blocks 94-96 as well. Notice in FIGS. 14A-14C that stackable drive block 98 comprises the generally rectangular internal aperture 101. The mating stackable drive block, stackable drive block 100 in the illustration, comprises a male projection 103 that is generally rectangular and mates with and complements the shape of the aperture 101 and is received in the aperture, and it defines the generally rectangular area 111. During use, it is important to note that the paddle 104 comprises the end 104 c that is mounted on top of the stackable drive block 98 in the illustration. A pair of male projection locators 104 e (FIGS. 14A and 14B) are adapted to be received in locating apertures 98 f in stackable drive block 98 and in locating apertures 100 f (FIG. 14A) in stackable drive block 100. After the paddle 104 is mounted on to the stackable drive block 98, the mating block 100 is mounted on top of the stackable drive block 98 and traps or secures the paddle end 104 c between the stackable drive blocks 98 and 100 as illustrated.

Notice in FIGS. 14B-14G that the paddle 104 is adapted to receive the air bag 106 that comprises the connector 121 that couples the airbag to a paddle conduit 104 g (FIG. 14C). The paddle conduit 104 g becomes in fluid communication with the block conduit (conduit 98 a in the example). The nipple or raised projection 104 d cooperates and depresses the air valve 117 in order to couple the passageway 98 a to the paddle conduit 121 a. As described herein, once the paddle 104 is mounted to one of the stackable drive blocks 94-100, its conduit is also coupled and in fluid communication with the conduit of the block to which it is coupled, which also puts it in fluid communication with the conduits of other stackable drive blocks 94-100 used and also conduit 112 b of the air delivery shaft 112 and ultimately the pneumatic air supply 119.

It should be understood that each of the drive blocks 94-100 have aligning and locking apertures, such as the aperture 98 f (FIG. 14A) on stackable drive block 98 that extends therethrough. After the stackable drive blocks 94-100 are mounted on top of each other and mated as described herein, the desired number of paddles 104 are mounted to one or more of the stackable drive blocks 94-100, the pair of bolts 93 (FIG. 14A) may be positioned and extend through all of the stackable drive blocks 94-100 and ultimately screwed into mating female threaded apertures (not shown) in the support block 92, thereby securing all of the stackable drive blocks and the paddles thereto.

As mentioned earlier, once the stackable drive blocks 94-100 are stacked, their conduits become in fluid communication and in fluid communication with the air delivery shaft 112 and ultimately the pneumatic air supply 119. Notice in FIG. 14 that the last block, namely stackable drive block 94, does not have a through aperture in the male projection 103 because it is mounted on the support block 92. In contrast, note that the stackable drive block 98 does have the passageway 98 a. Because the stackable drive block 94 is supported directly by the support 92, it is the last stackable drive block that is adapted to supply air to any paddles 104 connected thereto because the support block 92 does not have any pneumatic apertures unlike the stackable drive blocks 94-100.

As described herein, after the turbine engine component or part 12 is mounted onto the support plate 26, the required number of support blocks of stackable drive blocks 94-100, the support block 92, air delivery shaft 112 and the like are all assembled to provide the pneumatic manifold assembly 59 inside the turbine engine component or part 12 and the paddles 104 positioned and mounted on the stackable drive blocks 94-100. The assembled stackable drive blocks 94-100, paddles 104, drive shaft extension 54 a and the like are all then secured together and mounted onto the drive shaft 54 using the drive shaft extension 54 a. After positioning of the turbine engine component or part 12 and assembly of the stackable drive blocks 94-100 and paddles 104 and the drive shaft extension 54 a mounted onto the primary drive shaft 54, then the operator may start the turbine engine component cleaning system and process 10 which causes the drive motor 52 to rotate the entire manifold and support 92 and all the stackable drive blocks 94-100 so that the bags 107 on the paddles 104 can scrub, clean and/or polish the surfaces 12 a in the manner described herein.

In the embodiment of FIGS. 14D-14E, the same parts are identified with the same part numbers, except that one or more prime mark(s) have been added to like part numbers for the different embodiment. FIG. 14D illustrates another embodiment of at least one paddle 104′, except that this paddle 104′ comprises a first hinge member 157′ and a second hinge member 159′ that are adapted to pivot about axis B (FIG. 14D) to allow insertion into the tight spaces of the turbine engine component or part 12′, for example, by bending around a tight corner. Once inside the turbine engine component or part 12′, it can be pivoted back into its original straight or planar configuration so that it acts like a normal paddle 104′ depicted in the other embodiment.

As is illustrated in FIG. 14D, the paddle 104′ comprises the first hinge member 157′ and the second hinge member 159′ are hingeably attached together with a pair of pivot pins 153′ that permit the first and second hinge members 157′ and 159′ to pivot with respect to each other in the direction of double arrow B. Note that the paddle 104′ comprises a pair of planar surfaces 155′ that are generally opposed and that define a channel 158′ through which the air bag 106′ may pass after it has been coupled to the nozzle 121′. During use, it may be required that the paddle 104′ be pivoted and then moved into a particular position and then unpivoted, for example, as illustrated in FIG. 14E. It has been found that the hingeable paddle 104′ provides the ability to maneuver the paddle 104′ into position inside the turbine engine component or part 12′.

FIG. 15 is a schematic illustration of a general procedure or process for cleaning the plurality of surfaces 12 a of the turbine engine component or part 12. The procedure begins at block 150 where the user places and secures the turbine engine component or part 12 to be cleaned on the locators 72, 73. After the user positions the turbine engine component or part 12 onto the locators 72, 73 the user then secures, by conventional fasteners or bolts, the turbine engine component or part 12 onto the locators 72, 73.

After the turbine engine component or part 12 is secured, the routine continues to block 152 wherein a predetermined number of the stackable drive blocks 94-100 are stacked onto the support block 92. In this regard, the user stacks at least one or a plurality of the stackable drive blocks 94-100 onto the support block 92 in response to the number and position of the plurality of surfaces 12 a to be cleaned. In this illustration, note that the turbine engine component or part 12 has pairs of generally parallel and opposing plurality of surfaces 12 a as shown in FIG. 9 . In the illustration being described, these surfaces are generally parallel, but as mentioned, they do not have to be or they could be spaced, interior, generally parallel, non-parallel, radial, perpendicular, arcuate, interrupted, polygonal or the like.

Thereafter, the routine continues to block 154 where a predetermined number of the paddles 104 are situated or detachably mounted to the stackable drive blocks 94-100. It should be understood that the paddles 104 may be detachably mounted onto the stackable drive blocks 94-100 prior to the stackable drive blocks 94-100 being stacked, but in the embodiment being described, the stackable drive blocks 94-100 are first stacked and then the paddles 104 and their associated air bags 106 and bags 107 are detachably mounted (block 156) to the stackable drive blocks 94-100 in response to the plurality of surfaces 12 a to be cleaned. Once the paddles 104 are mounted onto the stackable drive blocks 94-100 and the stackable drive blocks 94-100 are stacked as illustrated, notice that the air bags 106 become positioned in generally opposed operative relationship with the plurality of surfaces 12 a to be cleaned as illustrated in FIG. 9 .

The operator then mounts the locking plate 80 (block 158) to the turbine engine component or part 12 using the fasteners 110. Note that a bearing assembly 127 on the locking plate 80 rotatably supports the air delivery shaft 112 during rotation and after the locking plate 80 is mounted onto the turbine engine component or part 12 as explained earlier. As mentioned earlier, notice that the turbine engine component or part 12 remains stationary as the stackable drive blocks 94-100 and their associated paddles 104 and the inflatable air bags 106 are rotated.

The routine continues to block 160 wherein the operator actuates the switch 34 a to energize the turbine engine component cleaning system and process 10 and energizes drive motor 52 to rotate the pneumatic manifold assembly 59 inside the turbine engine component or part 12. Once the user turns the turbine engine component cleaning system and process 10 on, the pneumatic air supply 119 and drive motor 52 are energized and the air bags 106 become inflated. The various conduits from the pneumatic air supply 119 (e.g., 112 b, 98 a and 100 a in FIG. 11 ) enable and cause the air to be delivered to the stackable drive blocks 94-100 and to any paddles 104 and air bags 106 secured thereto. The air regulator 122 controls the pneumatic air supply 119 and is adjustable so that the user may control the PSI delivered to the air bags 106. In one embodiment, the preferred air pressure supplied to the air bags 106 is about 2-5 PSI, but it could be higher or lower depending upon the air bag 106 itself. Before the turbine engine component cleaning system and process 10 is energized, however, the bags 107 are placed over the air bags 106 and paddles 104. Once inflated, the air bags 106 cause their associated bag 107 to engage at least one or a plurality of surfaces 12 a to be cleaned with a predetermined amount of force. In general, the air bags 106 are inflated to about 2-3 PSI, but total force will be determined by the number of paddles 104, the type of air bags 106 used, as well as the desired contact pressure at which the air bags 106 engages the plurality of surfaces 12 a to be cleaned. The operator then actuates the switch 34 a which causes the motor to be energized, which in turn causes the paddles 104 and associated air bags 106 to rotate inside the turbine engine component or part 12 and on the plurality of surfaces 12 a (block 162). In the illustration being described, the drive motor 52 drives the paddles 104 at approximately 15-20 RPMs and in one preferred embodiment, 17 RPMs. For example, notice in FIG. 9 , that the plurality of surfaces 12 a to be cleaned are generally opposing in one example. After the operator places the paddles 104 on the stackable drive blocks 98-100, the air bags 106 become situated in operative relationship with and between the plurality of surfaces 12 a to be cleaned. When the air bags 106 are inflated, the air bags 106 force the bags 107 to engage both surfaces 12 a so that when the drive motor 52 is energized, it causes each of the inflatable air bags 106 to engage and wipe, scrub and/or polish both surfaces 12 a as the drive shaft 54 is rotated.

After cleaning, scrubbing and/or polishing, the plurality of surfaces 12 a, the stackable drive blocks 94-100, paddles 104 and air bags 106 are disassembled (block 164). The locking plate 80 and air delivery shaft 112 are dismounted (block 166) from the turbine engine component or part 12 and stackable drive block 100. At decision block 168, it is determined if further processing of the turbine engine component or part 12 is needed or if the bags 107 need to be replaced. If further processing step(s) are needed or if the turbine engine component or part 12 needs to be cleaned again, then the routine continues to block 170 as shown. If no further processing is needed, then the processing is completed at block 168 and thereafter the routine ends.

In the illustration being described, the user causes the drive motor 52 to be energized for a predetermined amount of time necessary to clean the plurality of surfaces 12 a. The predetermined amount of time will depend on the amount of cleaning required, the bags 107 being used, the amount of frictional force or PSI that the bags 107 engage the plurality of surfaces 12 a to be cleaned, scrubbed or polished, which, in turn, results from the amount of fluid or air delivered to the inflatable air bags and the like. The PSI may be adjusted using the air regulator valve 122 (FIG. 5 ).

In general, the turbine engine component cleaning system and process 10 is energized for a predetermined amount of time as necessary to clean the plurality of surfaces 12 a and in at least one embodiment, the predetermined time is less than about 30 minutes, and generally less than about 15 minutes. In contrast, it is important to note that the amount of time necessary to clean the same or a similar part in the prior art was on the order of about 3-5 hours.

In the illustration being described, the bags 107 are Scotch-Brite™ pads and are disposable or replaceable. It should be understood that a different abrasive material could also be a flexible cloth abrasive or any other flexible abrasive material.

Also, note in another embodiment of FIGS. 14F-14H that one or more permanent or detachable strips 107 a′ may be detachably secured, permanently secured or integrally formed with the bag 107′ which covers air bag 106′. In this embodiment, the bag 107′ has the strips 107 a′ that are detachably secured, permanently secured or integrally formed thereto. For example, note that the distal edge 107 b′ of the bag 107′ has the added strips 107 a′ to reach areas where the air bag 106′ is not able to pneumatically push a traditional bag 106 of the type shown and described earlier herein. The bag 107′ with the strips 107 a′ facilitates cleaning, polishing or scrubbing areas, such as radii and corners of the engine component or part 12′. Again, the strips 107 a′ can be detachably secured, permanently secured or integrally formed with the bag 107′ or separate or detachably secured thereto (e.g., with Velcro®, adhesive or the like) where necessary or desired, as illustrated in FIG. 14H. Note in FIG. 14H that the strips 107 a′ could extend beyond the boundaries of the bag 107′.

In some embodiments, it may be necessary to replace the bags 107 after every cleaning. In other embodiments and depending upon the amount of dirt or corrosion on the turbine engine component or part 12, it may be that the bags 107 can be used multiple times.

Advantageously, in one embodiment the turbine engine component cleaning system and process 10 is adapted to drive the paddles 104 at about 17 RPM, with an air bag 106 pressure of about 2-5 PSI. If desired, the paddles 104 may be driven at the same speed and pressure. Alternatively, they could be driven at a different speed, such as at intermittent speeds and utilizes a different pressure against the surfaces 12 a.

Advantageously, another embodiment of this invention, including all embodiments shown and described herein, could be used alone or together and/or in combination with one or more of the features covered by one or more of the claims set forth herein, including but not limited to one or more of the features or steps mentioned in the Summary of the Invention and the claims.
